Letters Patent No. 93,871, dated August 17,'1869.

hdm-- -To all whom vit may concerny Be it known that I, Josemi FUNCK, of Tompkinsrille, in the county ot' Richmond, and State oi' N ew York, hure invented :i new and improved H ydmulic FloatfLarnp; and l do hereby declare the 'ollowingto be :i full, clear, and exact description thereof, which will enable those skilled in the nrt to make and use the same, reference being had to the accompanying drawing, forming part of this' specification, iu which drawing- Figure l represents a side elevation of my lamp when put up for use.`

Figure 2 is u. central section of the regulating ioatmechanism in a, larger scale than theprevions figure.

Figure is e. horizontal section of' the same.

Similar letters indicate eorrmpoilding parts.

This invention consists in he arrangement of an adjustable float und valve in 'he oil-supply pipe of' a lamp, in such a manner that by the combined action otsuid out and' valve, the supply of' oil to the wicktnhe is regulated, vund the oil supplied automatically, just as fast as it its consumed. 'Ihe valve and valvesteui are both notched and gnooved, and said stein is secured in a cross-bar or bridge in a tubular space in the iioat, in such n manner that the oil, on passingY down from the supply-pipeintothe dont-chamber, will trickle down on the valveseni wit-houtconiingin coutact with the surface of the float, and the weight of the iioat is not changed by the oil which would necessarily adhere to said tioat if it should be permitted to run down over the surface ol'the same.

In the drawing, the letter A designates the Wicktube or burner, which connects, by a channel, a, with a chamber, B, enclosing the dont C.

A suitable stop-eock, b, serves to close the channel u, whenever it is desirable to take ofi' the wick-tube.

The float. l is perforated throughout its lcngthwith a tubular spzufe, c, and it; is suspended from :L rod, d, `which screws into one or more cross-hars or bridges, c, and to the upper end of which is secured a conical valve, f.

This valve is enclosed in a voire-chamber, y, which communicates with the. float-chamln'r B through a channel, li, and with the supply-pipe D through :i channel, i, as shown in fig. 2 ofthe diawingf vVlxen the oil in the Heat-chamber B rises to :i certain level, the float is raised to such a height that the valve f closes the supply-elimine! i', and the further supply oi'oil is stopped, but if the oil sinks down in the Hoot-c1iumbcr, the valve is carried down by the gravity of the float, and it restson top ofthcehunnel h.

f minir relatively to chambers,

l The oil, however, runs past; the valve through said channel into the {inet-chamber, both the valve and its stem being provided with notches or grooves, so that the oil will trickle down through these grooves, and thereby be prevented from accumulating on the bridges e, or ou the surface ut' the liet, whereby thc specific gravity of the tient would be changed, and its correct operation impaired.

The supply-pipe Dis intended to connect with a suit-able reservoir, as indicated in iig, 1, and if' the eomiiiunicatiou between this reservoir and the supply pipe is opened, the oil iows down to the burner just :is fast as it is consumed by the thune, and no further attention is required as long as the reservoir contains a sufficient supply of oil.

This lamp is intended particularly for light-house purposes, where the burner is placed opposite to a refiector, and a snflicient supply of oil must be provided to supporty the flume during the whole night. The oil, reservoir, therefbl'c, must be of considerable capacity, and if it should be plrwed in the iield ci' the refiector, in would necessarily decrease its effect.

By my improvement, I :im enabled to feed the oil to thehnrner, with the requisite regularity, from a reservoir situated at any desired height above said bui-nei, the float being so adjusted that it; allows the ovcrllow to control the correct action of the feedingnxechanisin.

When t-hc oil has reached the required level, the float carries the valve f up into the channel i, and the supply of oil is momentarily stopped, until the flame has consumed n sxnall portion ofthe oil in the burner, then the dont sinks down, and the supply of oilis recstablishcd.

Having thus described 1n y invention,

What I cla-iin :is new, and desire to secure by Letters Patent, ise 1 The. nrralngenicnt w i t hin the separatcdoil-chamber B, ol' the tubular float G, suspended from rod d, which carries n valve, f, playiini,r iu a chamber, g, and operh the parts being combined substantially and for the purpose as described.

. 2. The arrangement of not-ches or grooves in the valve und. its stem, in combination with thc bridges e. lient C, and channel h, substantially ns set forth. 1
